B+W 49mm Master HTC KSM Circular Polarizer MRC Filter

OVERVIEW

B+W polarizing filters are circular polarizers which are compatible with nearly all modern cameras when beam splitters are used in the light path for TTL exposure metering or autofocus. Exposure errors are therefore avoided. The multiplying factor with HTC is 2 to 3, which is equivalent to 1 to 1.5 f-stops. Other polarizers up to approx. 3 stops. Often regarded as the most important filter for photography.

• Grease-free polarizing filter for easy rotation
• Easier to attach due to new varnish technology
• Durable and robust due to brass mount
• For all lenses with front thread
• Optimal for super wide angle to telephoto lenses
• Made in Germany
